Eartha, the world's largest rotating and revolving globe, is located within the headquarters of the DeLorme mapping corporation in Yarmouth, Maine. The globe weighs approximately 5,600 pounds (2,500 kg), and has a diameter of over 41 feet (12.5 m). This gives it a scale of 1:1,000,000, on which one inch represents 16 miles, one millimetre represents one kilometre. As with most globes, it is mounted at a 23.5 degree angle, the same axial tilt as the Earth itself; thus the equator is diagonal to the floor. It uses a cantilever mount with two motors, and simulates one day's revolution and rotation every minute.
The globe was completed on July 23, 1998, and it uses a composite database built from satellite imagery, shaded relief, colored bathymetry, and information about road networks and urban areas. The database used to generate the surface images was approximately 140 gigabytes.
